You can find more information about each of these items in the attached proxy statement. Only holders of common shares registered in the register of members at the close of business on November 22, 2024 (the “Record Date”) can vote at this meeting or at any adjournment thereof that may take place. Each common shareholder has one vote for each common share held as of the close of business on the Record Date. Holders of record of the Company’s American Depositary Shares (“ADSs”) at the close of business on the Record Date who wish to vote the common shares represented by the ADSs must act through JPMorgan Chase Bank, N.A. as depositary of the Company’s ADSs program. Each ADS represents 20 common shares.

We cordially invite all shareholders to attend the annual general meeting in person. However, a shareholder entitled to attend and vote is entitled to appoint a proxy to attend and, on a poll, vote instead of such shareholder. A proxy need not be a shareholder of the Company. Whether or not you expect to attend the annual general meeting in person, please mark, date, sign, and return the enclosed proxy card as promptly as possible to ensure your representation and the presence of a quorum at the annual general meeting. If you send in your proxy card and then decide to attend the annual general meeting to vote your shares in person, you may still do so. Your proxy is revocable in accordance with the procedures set forth in the proxy statement. This proxy is to be delivered to the attention of the Office of the Board of Directors, Xinyuan Real Estate Co., Ltd., 27/F, China Central Place, Tower II, 79 Jianguo Road, Chaoyang District, Beijing 100025, the People’s Republic of China, and arrive no later than 48 hours prior to the meeting.

PROXY STATEMENT

General

We are soliciting the enclosed proxy on behalf of our board of directors for use at the annual general meeting of shareholders to be held on December 19, 2024 at 10:00 a.m. local time, or at any adjournment or postponement thereof. The annual general meeting will be held at Xinyuan (China) Real Estate, Ltd., 27/F, China Central Place, Tower II, 79 Jianguo Road, Chaoyang District, Beijing 100025, the People’s Republic of China.

This proxy statement is available to shareholders beginning on November 22, 2024, and the form of proxy is first being mailed to shareholders on or about November 22, 2024.

Revocability of Proxies

Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before its use by delivering a written notice of revocation or a duly executed proxy bearing a later date or, if you hold common shares, by attending the annual general meeting and voting in person. Attendance at the annual general meeting in and of itself does not revoke a prior proxy. A written notice of revocation must be delivered to (i) the attention of the Office of the Board of Directors, at our offices in Beijing at the address listed above, if you hold our common shares, or (ii) JPMorgan Chase Bank, N.A., Depositary, PO Box 64873 Saint Paul MN 55164-0873, if you hold American Depositary Shares, known as ADSs, with each ADS representing 20 of our common shares.

Record Date, Share Ownership, and Quorum

Shareholders of record at the close of business on November 22, 2024 are entitled to vote at the annual general meeting. Our common shares underlying ADSs are included for purposes of this determination. As of November 22, 2024, 177,326,400 of our common shares, par value US$0.0001 per share, were issued, of which 63,563,366 were held by the Company as treasury shares and 113,763,034 were outstanding. Approximately 74,405,372 shares were represented by 3,720,269 ADSs. As of November 22, 2024, unexercised options with respect to 108,704 ADSs were reserved in our employee stock option plan. The presence in person or by proxy of at least 20 shareholders holding not less than one-half of our outstanding common shares entitled to vote at the meeting will constitute a quorum for the transaction of business at the annual general meeting.

Voting and Solicitation

Each common share outstanding on the record date is entitled to one vote. Voting by holders of common shares at the annual general meeting will be by a show of hands unless the chairman of the meeting or any shareholder present in person or by proxy demands that a poll be taken. Holders of ADSs cannot vote at such meeting.

The costs of soliciting proxies will be borne by our company. Proxies may be solicited by certain of our directors, officers, and regular employees, without additional compensation, in person or by telephone or electronic mail. The solicitation materials are available on our company’s website at http://ir.xyre.com/news-events/agm-summary. Hard copies of the solicitation materials are available upon request to shareholders free of charge.

Voting by Holders of Common Shares

When proxies are properly dated, executed, and returned by holders of common shares, the shares they represent will be voted at the annual general meeting in accordance with the instructions of the shareholder. If no specific instructions are given by such holders, the proxy will vote the shares in his or her discretion, unless a reference to the holder of the proxy having such discretion has been deleted and initialed in the form of proxy. Where the chairman, a director, or an officer of the company acts as proxy and is entitled to exercise his or her discretion, he or she is likely to vote the common shares “FOR” Proposals 1 and 2. Abstentions by holders of common shares are counted as present for the purpose of determining whether a quorum is present and are not counted as votes for or against a proposal.

Voting by Holders of American Depositary Shares

JPMorgan Chase Bank, N.A., as depositary (the “Depositary”) of the ADSs, has advised us that it intends to mail the Notice of 2024 Annual General Meeting of Shareholders and an ADS Voting Instruction Card to all record date holders of ADSs. Upon timely receipt by the Depositary of a signed and completed ADS Voting Instruction Card properly executed by a record date holder of ADSs, the Depositary will vote or cause to be voted the number of common shares represented by the ADSs held by such holder in accordance with the instructions set forth therein. If you mark the box in the enclosed ADS Voting Instruction Card instructing that you wish to give a discretionary proxy to a person designated by the company, the underlying common shares represented by your ADSs will be voted by a person designated by the company in his or her discretion. In accordance with the provisions governing the ADSs, the Depositary will not vote the common shares represented by the ADSs other than in accordance with such instructions. If (i) your enclosed ADS Voting Instruction Card is signed and dated but is missing specific voting instructions or (ii) your enclosed ADS Voting Instruction Card is improperly completed, the Depositary will not vote the underlying common shares represented by your ADSs.

As the holder of record for all the common shares represented by the ADSs, only the Depositary may vote those shares at the annual general meeting. Properly executed and delivered instructions to withhold votes and abstentions are counted as present for the purpose of determining whether a quorum is present and are not counted as votes for or against a proposal. You should return your properly completed ADS Voting Instruction Card to the Depositary prior to 9:00 a.m. (Eastern Standard Time) on December 18, 2023, which is the last date by which voting instructions may be received by the Depositary.

Neither the Depositary nor its agents are responsible if they fail to carry out your voting instructions or for the manner in which they carry out your voting instructions. This means that if the common shares underlying your ADSs are not able to be voted at the annual general meeting, there may be nothing you can do.
